AR-15 Gas System

How much power is lost from this

Totally inefficient. Exactly why the forward assist was added.

Why the AK47 is a superior wespon. The gas is routed directly to the piston head. Shoving it back with far less power loss.

Not to mention the toght tolerances. Again totally inefficient. Prone to jamming when slightly dirty.

Tbh looks like AK system but with very long tube

That’s not an ar-15 it’s a m-16

Learned from Russia

These comments are hilarious 🤣

Bad bad system . When you need it , it will jam , many soldiers are dead because of that .

"WtF are you guys all tal"

I see error

Hey bro, how does an AR-15 wor-

So underwater it won't work normally ...

Given that your definition of dwell time is not correct........ I don't think that watching any of your other videos is a good idea.

Dwell time is the amount of time that the gas is having any kind of an effect whatsoever on your firearms operating system. It is not only the amount of time between the entry of the gas port to the end of the muzzle. That is a common misconception and it is not true.

“Wait, lemme just bring my newborn onto the airpl-“

Very good rifle design. One of many reasons they are so popular in the US.

Does this fail often?

So if your gas system is too short in relation to your barrel, its very easy to over gas. Cool. I know this now.

The designer was in the zone with his invention.

Hey Matt I know it's been 7 months
But can you make aa12 work

so direct impingement like the AR or short piston like the HK? Which one is more reliable and in which condition?

Why is this gun called M-4 or M-16 in games?

Good video, but you failed to state that during the dwell time the carrier is moving. The cam groove in the carrier acts upon the cam pin that passes thorough the bolt body. This rotates the bolt to allow unlocking at the point the vent holes uncover.

I Heard there’s someone in the tr-

"I am a strong independent wom-"

Now do D.I. direct impingement

Technically dwell time is the time gas pressure acts on the cycling system aka BCG.

Always wondered how you clean that

😮

I will never understand why the U.S. military chose this overly complicated rifle instead of a simpler model.

Eugene Stoner is a true genius of mankind. He thought up that entire system and worked out the pressure and volume math to make it work in it's simplest form.

Can someone explain to me how the gas makes the cam-pin unlock it

It’s amazing all this happens when you right click your mouse 😂

So much more complicated than the ak47

Matt, while the gas does impart a force onto the BCG, it simultaneously does it to the bolt. this forward force is maintained as the BCG moves rearward, and relieves the pressure on the bolt lugs as the rotate and unlock from battery

is there a seal between gas key and gas tube?

Since I shoot left handed all the gas goes in my face 😂

The best gas spreading system

Famas

The only thing missing about the bolt carrier group is how, when the bolt carrier travels back as the internal chamber pressurizes, the bolt get turned by the cam pin to unlock it.

This is the best animation - along with the narration - I've seen regarding this specific part of the process.

Dwell time is NOT the amount of time the bullet spends between the gas port and the muzzle its how long the gas takes to start the action cycle. Were measuring gas time not bullet time. The longer the has system the longer the gas takes to get to the bolt and vice versa. Thats why a carbine gas system has the most pressure getting into the action because it is retaining the most energy because of the short pathway.

Dwell time isnt really much of a thing anymore. I remember they said you have to have thia barreof a barrel and gas hole in this spot or it wonr cycle rright. Well now and days all those issues have been ironed out

The amazing part is that the gas both moves die bolt carrier back, while pressing die bolt itself forward. You could say it both unlocks with gas and delays the unlocking with gas!

Solo pon un resorte de ese diámetro ay y tendrás tu cabeza activa al salir tu 2 ollitos respiraderos con trabajos se alcansara a ver y tendrás todo el impulso del mundo

O voltiamos esa cosa y listo

How do you create your illustrations

This is the key to the Stoner internal piston system. It keeps all the recoil energy inline with the shooter's shoulder as well, making felt recoil minimal. The original AR video kinda skipped over this, so I'm glad to see this going into more detail!

This is super complicated. I wanted to build a semi auto bolter in 50 Beowulf but this is crazy complex.

long time no see, this is excellent mate

Fascinating design and your video describe it perfectly to be able to clearly understand the Gas System. Makes trouble shooting it much easier too. Thanks.
